AUSTIN, Texas — A recent survey of over 1,000 individuals conducted by EyeBuyDirect, the fastest growing online prescription eyewear retailer, found 4 in 5 people spend five or more hours a day looking at a screen, with a third in front of a screen for eight hours or more. The company recently introduced SightRelax(TM), a new line of digital-protection lenses with the blue-light filter, scratch-resistant and anti-glare coatings, and UV protection.
